Helloo!
I'm working on creating a puzzle on wpf and I need some help in saving pieces of a picture in a specific folder to reload them if the user requested..
1. I checked if the directory exists
2. if not, I wrote:

C#

if (!Directory.Exists(path1))
              {
                  Directory.CreateDirectory(path1);}

3. I need to save pieces into the previous folder! I got the Original Image from an open file dialog then I cut it into 100 pieces at run time

Anyway
Can Anyone help me saving an image in a folder?

The Image class directly has a Save method you can use. See:http://msdn.microsoft.com/en-us/library/ktx83wah.aspx[^]

Thank you ! But isn't what you gave me for Windows form not wpf?
because I already tried it but (image1.Save) didn't exist!

Actually it's a GDI+ class. But if you're using WPF Image class directly then perhaps an easier way would be to encode it directly. Have a look at this article: http://blogs.msdn.com/b/kirillosenkov/archive/2009/10/12/saving-images-bmp-png-etc-in-wpf-silverlight.aspx[^]

The process cannot access the file because it is being used by another process.
I Always Get this error ! I know I have to dispose the Image but how?
I used this one!
the framework elememt can be a type Image right?

void SaveToPng(FrameworkElement visual, string fileName)
{
var encoder = new PngBitmapEncoder();
SaveUsingEncoder(visual, fileName, encoder);
}

void SaveUsingEncoder(FrameworkElement visual, string fileName, BitmapEncoder encoder)
{
RenderTargetBitmap bitmap = new RenderTargetBitmap(
(int)visual.ActualWidth,
(int)visual.ActualHeight,
96,
96,
PixelFormats.Pbgra32);
bitmap.Render(visual);
BitmapFrame frame = BitmapFrame.Create(bitmap);
encoder.Frames.Add(frame);

using (var stream = File.Create(fileName))
{
encoder.Save(stream);
}
}

What I did was cutting the original image into pieces
each piece i memorized its data in a struct
struct ImagePuzzle
{
public System.Windows.Controls.Image pieces;
}
At the end I want to save each piece in a specific folder !
But I'm getting the previous error because I guess I have to dispose them !
How Can I do such thing?

Try
http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.bitmapencoder.aspx[^]
to Encodes a collection of BitmapFrame objects to an image stream.

FileStream stream = new FileStream("empty.tif", FileMode.Create);
TiffBitmapEncoder encoder = new TiffBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(image));
encoder.Save(stream);

as you can use given function

C#

public static void SaveClipboardImageToFile(string filePath)
{
    var image = Clipboard.GetImage();
    using (var fileStream = new FileStream(filePath, FileMode.Create))
    {
        BitmapEncoder encoder = new PngBitmapEncoder();
        encoder.Frames.Add(BitmapFrame.Create(image));
        encoder.Save(fileStream);
    }
}
